Vacuum stops and displays E9 or nine red flashes when using motorised accessories

Safety: Remove the battery and detach all accessories before inspection.

• Identify the faulty tool: Run the vacuum with no accessories. If it works, attach each motorised tool (mini turbo brush, pet tool) one at a time until E9 appears. The last tool attached is likely faulty.
• Check for jams: On the suspect tool, remove the brush roll and clear hair, string, and debris. Ensure the brush spins freely.
• Inspect wiring and connector: Look for bent pins, loose wires, or burn marks at the accessory connector.
• Test again: Reassemble the tool and test. If E9 recurs only with that accessory, its motor or internal electronics are damaged.
• Replace accessory: Replace the faulty Hoover H-Free motorised accessory with a genuine part.
